Here's a good place to start. We're off to Normandy tomorrow for the umpteenth time with the boat. Technically you don't need much, but that doesn't mean to say the French won't ask for it, they LOVE paperwork & "leesonces"
I take:-
SSR Cert + fly the red ensign
VAT invoice from when I bought the boat (copy)
Ships VHF licence
Personal VHF cert
ICC
Insurance
PS We'll be in Barfleur from Saturday if you want to give us a shout, we'll be setting up on Sat but will hopefully be on the water Sunday.
